Solid mineral wastes from mines, mills, and smelters are potential or active contributors to air and water pollution and, together with accumulations of automobile scrap, detract from the beauty of our landscape. Bureau of Mines researchers are seeking means for utilizing or stabilizing mineral waste and for recycling or economic use of automobile scrap. Studies have been directed to (1) production of copper from dump leach solutions using shredded auto scrap as a cementation medium, (2) recovery of zinc from foundry dusts, (3) recovery of additional values from copper and uranium mill wastes, and (4) production of ceramic and construction materials from waste products. Stabilization studies employing physical, chemical, vegetative, and combination techniques also have been made. A 34-acre uranium waste accumulation has been stabilized using an elastomeric polymer and a calcium-magnesium lignin sulfonate as chemical stabilizers. Ten acres of copper mill tailings also have been effectively stabilized using a resinous adhesive compound in conjunction with selected vegetation in a combination chemical-vegetative method.
